For alleviating acid mine drainage arising from oxygenated water passing through pyrite, the water is de-oxygenated in an intercepting protective layer, which comprises a mixture of grains of pyrite and grains of iron. The grain sizes, concentrations, etc are selected to create an ensemble of galvanic cells at the points of contact between the iron grains and the pyrite grains. The pyrite cathode material becomes cathode-protected, and the water becomes de-oxygenated, by the electrolytic action.
